This paper presents a method of improving the attitude determination accuracy for nanosatellites with the aid of the camera sensor. In typical mission, the star tracker is usually used as an optical sensor for the precise attitude pointing for the nanosatellite. However, mostly, the star tracker cannot be affordable for most of the missions because of its cost. Instead of using the star tracker, the...
This paper presents target motion estimation for multiple air vehicles. The motion of the airborne target is estimated by vision information from camera sensors fixed to the followers. Each camera sensors provides information of the target by three angles: an azimuth angle, an elevation angle, and a subtended angle. In the frame work of information filter, each follower estimates position, velocity...
Using Fisher Information Matrix (FIM), the optimal trajectory to localize a specifc target is obtained as optimization problem. However, it is more effective to employ more vehicles with various sensors in order to gather suffcient information about the target. So, it is investigated how multi vehicles with different types of sensors by cooperative maneuver affect the trajectory in this paper. Clearly...
